Real Scale Fire Test for the Karaoke Fire Risk Analysis

Abstract

Karaoke is the structural feature that it is located underground or composed of no window layer secret room even over the ground so that it has quite high risk of airway obstruction due to smoke at the fire. In this study, a real scale fire test was performed for actual karaokes at the zone under reconstruction. The results showed that oxygen concentration of the room at which fire occurred decreased to 13.99% around 5 minutes later, and 0.58% of carbon monoxide was generated. Especially, 0.8% or more of carbon monoxide was measured in the room next to it around 8 minutes after fire occurrence. Thus, it was found that air way obstruction would probably occur due to toxic gas such as carbon monoxide by incomplete combustion of sound proofing material rather than flame spread by fire re-spread. Consequently, fatal toxic smoke reaches the surrounding space in around 3 minutes without quick early measures at the fire of sealed room so that many causalities result.
